Abstract: | In this paper, we propose and numerically demonstrate a highly birefringent microstructure optical fiber which shows negative dispersion coefficient of about −288 to −550 ps/(nm km) covering S to L wavelength bands and −425 ps/(nm km) at the excitation wavelength 1550 nm. This proposed design successfully compensate the dispersion covering S to L communication bands ranging from 1460 to 1625 nm along with relative dispersion slope (RDS) perfectly matched to that of single mode fiber of about 0.0036 nm−1. Apart from dispersion compensation, the designed MOF offers high birefringence of 2.94 × 10−2 at 1550 nm and better compensation ratio with design simplicity due to circular air-holes in the fiber cladding. |
